-tilpecification formingpart of Letters Patent No. 2 I 0.091, dated November 19, 1878'; application filed I August 31, 1 877.

Be it known that 1, ANDREW BURGESS, of O'we'go, in the county-of Tioga and State of New York, have invented a new and useful Improvement in Magazine Fire Arms, which improvement isfully set forth in the followifig specification, reference being had to the.

accompanying drawings.

' Theimprovements in this arm consist, principally, in the, method of operatingand look ing the breech-bolt, the construction of the carrier and feeding device, together with the general arrangement and combination of parts, a hereinafter more fully explained and described.

In the accompanying drawin gs,"*Fi gure 1 is a 1 side view of the arm, showin g some of its works -1n dotted lines.

I Fig. 2 represents a sectional side elevat on, and Fig. 3 a modification of the carrier and its operating device in sec- Similar letters of reference indicate corre sponding parts.

The receiver A contains a breech-bolt, B,

which is operated back and forth by the block L, provided with a thumb-piece, as in Fig. 1, or a guard-lever, as in Fig. 2. This blockbeing pivoted in the frame below the'breech bolt, extends upward through a mortise in the bi'eech-bolt, its upper end being split or slotted, to pass over the firing-pin and ejector; The mortise in the boltB is extended in a segment-down and forward, to allow the end of the block L'to fall under at B, when in its.

-most forward position to lock the bolt, the

projections 10 of the breech-bolt, together with I the top of frame, holding the bolt from rising.

It is obvious that thefiring-pin and ejector canbe split, that the block L shall pass between their two sides ;'or the bolt Bean be cu'taway'at its sides, and block'L mortisedor split to pass over it by mere change in construction.

' The carrier 0 is pivoted forward of the axis of thebreech-brace, (excepting in modification, Fig. 1, where a similar effect is produced by pivoting it in therean) and its forward end is caused to rise and fall by projections and depressions in circular part 0 of block L, outside of its pivot, operating against the point or points 0 of carrier, and to insure a positive effect; or when spring S is omitted,

the hook h is add'ed, as in Fig. 2.v o

In Fig.1 these variations in the segment 0' are ,reversed, to either. reverse the movement of carrier, or allow the pivot on of carrier to be placed back oflbreech-brace or leverpivot, as'at 12., instead of n, Fig 1.

' In dotted lines, at m, Fig. 2, is a modification by which the operating point ofearrier 1s The ejector'E, attached to t-heflfirlg-pin in such manner as to allow it some free IBGlPIO:

;;the firing-pin, or a IOll alongside or below it, andlias a part at E, projecting below the firing-pin. The firing-pin has twmshoulders, the one in front to keep it from coming. back too far, and the rear shoulder'is struck. by

back of breech brace, to force the pin back in the. movement of unlocking the breech. I

The breech-brace L is either continued in aguardlever, by which it is operated, or is providedwith a thumb-piece,.T, as in Fig. 1. In

S, which has the effect to presst'ne point a into a depression in the breech-brace, to hold it in a-locked or closed position.

To operatethis arm, after the magazine has ,been charged the guard-lever is firstturned forward or the'thumb-piece T pulled back, as the case may be. The first part of this movement raises the end of. breech-brace L from under the shoulder 13, therebyunlocking the breech-bolt, and allowing it to take a backward movement. At the same time the rear of block withdraws, the firing-pip by coming in contact witlfthe shoulderf, and then, reaching the shoulder 13, it pushes thebreech-bolt backward, which, pushing against thev haun -m'er,' cocks and then rides over it, and the ejector E, striking theface of the hammer, is

assistance of spring-stud E. At the same time the point 0 of carrier, entering the recess; 0', lowers the carrier to receive a cartridge from the magazine. Then the first part of the movement of closing the breech, raising the point 0 of the carrier onto the segment 0, lifts the cartridge to a level with the barrel andiu front concealed, and the carrier raised by the last part of the movement of opening the breech.

catin g movement, may be tubular, and inclose' Fig. 2-the carrier is pressed down by the springv stopped to expel the cartridge-shell by'the T AVARABIE COPY 2' etetoer of the breech-bolt, which, by its continued forward movement, drives the cartridge into the barrehcha'mber, and the end of breech-brace L, reaching the shoulder of segment at B, turns under it, which, by the assistance of the top of t'ra-meand ribs 12, looks the breech securely while the arm is being fired in the ordinary manner.

Having thusdeseribed my inyention, what I claim as new, and desire. s'ecnre by Letters Patent, is-- 1. The coinbinetimrote'mbrtiseil end shoul- 5 dared breech-bo1t with a pivote'dfleyer working n the mortise or againstithe-shonlders, to move and to look the bolt, sribst-anti'ztlly ca described. V j

2. The breech-bolt described, hzwingfai segmental surface, Eta-ml shoulder B1, in combination with the pivoted brace, to move and lock said bolt, substantially as specified.

3. A swinging brace locking the breechbolt eflfzth angle with the axis of the barrel, in combination with longitudinal ribs end grooves to resist the upward tendency of the breech-bolt, substantially as described.

4. The brace, the bolt, and the firing-pin, in combination, snbstantiallyas described, whereby the firing-pin is withdrawn by the unlocking of the brace.

5. The combination of the ejecting-pin and ham mer, arranged and operating-to expel the cartridge, substantially as'speeified.

6. A pivoted carrier provided with the point or points 0, in combination with the segmentor segments 0 of the pivoted lever, whereby the carrier is operated to rise and fell, substantially as described.
